You've heard the research, 40% of all tweets are useless babble, and social networks are being blamed for school-age kids' poor use of grammar. It is the constant joke in the media that all tweets must include "LOL" & "OMG." But is Twitter really useless?
Do you measure your television viewing because of the crap on TV, or never listen to the radio because there is a station you don't like? Writing off Twitter because of some people's updates makes as much sense as not using television advertising because of a program you don't like. I'm currently looking through the DirecTV guide, and out of the hundreds of channels to choose from, there may be 4-5 that I will ever select to watch. Meanwhile, I have run across hundreds of people on Twitter that are worth following. So which one is really the useless medium?
Just like any form of media, there are many different users, messages, and audiences. The key is to measure every media by the value it provides, not the irrelevant noise.
